High weatherability zinc-based inorganic anti-corrosive coating

摘要

The present invention relates to a high-weathering organic zinc-based rust preventive coating for steel materials used for steel structures such as various steel bridges, chemical plants, electric power facilities, etc. According to the present invention, spherical zinc powder: spherical aluminum powder: : 0.4 to 0.6: 0.02 to 0.08, and the spherical zinc powder: aluminum powder has a particle size ratio of 1: 2 to 4, And the size of the plate-type aluminum powder is 30 x 5 x 0.5 m in thickness. The double-layer sealing function of the spherical aluminum powder and the plate-type aluminum powder and the high-temperature electrical conductivity of the aluminum The method of preventing the damage of the coating for a long time by the continuous regeneration method of the zinc powder due to the zinc-aluminum mixed powder coating The.
